Aluminum nitride (AlN) ceramic substrate is a technical ceramic material with excellent performance, which has a wide range of applications in semiconductor, optoelectronics, aerospace and other fields.
Laser cutting is one of the important processes in the processing of AlN ceramic substrates, which has the advantages of fast cutting speed, high precision, and no pollution.

• High thermal conductivity: The thermal conductivity of AlN ceramic substrate can reach 170W/m·K, which is 5-8 times that of alumina ceramic substrate, and has good heat dissipation performance.
• High electrical insulation: The electrical insulation strength of AlN ceramic substrate can reach 1000V/mm, and it has good electrical insulation performance.
• High strength: The bending strength of AlN ceramic substrate can reach 380MPa, and it has good mechanical properties.
• High wear resistance: AlN ceramic substrate has good wear resistance and can withstand high-intensity friction.
• High corrosion resistance: AlN ceramic substrate has good corrosion resistance and can resist the erosion of various acid and alkali solutions.

• Fast cutting speed: Laser cutting is an efficient processing technology that can quickly cut out precise graphics and sizes.
• High precision: laser cutting has high processing precision, which can meet the requirements of complex graphics and dimensions.
• Burr-free: Laser cutting can achieve burr-free cutting and ensure the smoothness of the cutting surface.
• Pollution-free: Laser cutting is a clean process that does not produce pollution.

• In the field of power electronics: AlN ceramic substrates are ideal substrates for power electronic devices, and can be used for the packaging of power modules, IGBTs, MOSFETs and other devices.
